Requesting service manual for a Kenwood NV-701 Hifi system

I'm trying to find a service manual for a Kenwood NV-701 Hifi system. It is a 5.1 system with 3 disc CD, AM/FM tuner and Tape deck. It has 2 digital inputs and and is really cool. It currently isn't working and i know roughly what needs changing i just need to get hold of some part numbers to see if i can buy the spares locally in Australia.

Any help would be greatly appreciated
